This is the 13930th most frequent Korean word.
말하지만
"말하지만" means "but (speaking/talking)" or "although (speaking/talking)."
In this sentence, "말하지만" is used to contrast the action of speaking one's thoughts (말하다) with the seemingly ineffectual outcome.
나는 자주 친구들에게 내 생각을 말하지만, 아무도 듣지 않는 것 같아요.
I often tell my thoughts to my friends, but it seems like no one listens.
Here, "말하지만" connects the claim made by the subject (그가 말하다) and the observable lack of change.
그가 노력하고 있다고 말하지만, 실제로는 별로 변화가 없어요.
He says he is making an effort, but actually, there hasn’t been much change.
In this example, "말하지만" links the teacher’s statement with an unexpected result regarding students' performance.
